What are these small white spots on my seedling? Please help!

[215BegginingGrower]

Im new To growing and I have one particular question about my new weed plant. There are these white tiny spots along the first two leaves that sprouted and I’m neverous if there is something I’m missing. I use a desk Lamp with blue light at 100W about 4/5 inches away from the plant in a make-shift box with aluminum foil wrapped around except for the bottom where the plant sits. Please help I’m new to growing

Is that a discoloration in the leaf itself, or does that white stuff rub off???

Take a look under the leaf and see if there are black spots where the white spots are at the top. If so thems spidermites. If not I dont know peace

It’s within the leaf itself

I grow indoors is that possible to have indoor spider mites? And if so how to get rid of them for future reference

Within the leaf

Those are the cotyledons...throwaway leaves...all is good...only worry about the new ones after them...

 

[Mr. Krip]

Then, you should be fine. If it rubbed off, I'd worry about Powdery Mildew but as long as it's in the cotyledons themselves, as @Blew Hiller said, no need to worry.

I grow indoors is that possible to have indoor spider mites? And if so how to get rid of them for future reference

Yes, you can get spider mites inside and they are most active in warm weather. Spinosad (see "Captain Jack's Dead Bug" at one of the home centers) or any other OMRI listed miticide works. Neem is mildly effective as a preventative.

Oh yer its possible my friend

So disregard the discoloration because those two leaves will die anyway?

 

[Mr. Krip]

Yes. Those very first rounded leaves that emerge are called the "cotyledons". They're just providing some initial nourishment for the seedling until it develops roots and is able to uptake it's own nutrients. They will yellow and die by the time you hit the 3-5th node and don't be alarmed if it happens quicker!
